A lawyer's dog runs around town unleashed, heads for a butcher shop and steals a roast. The butcher goes to the lawyer's office and asks, "If a dog running unleashed steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?" The lawyer answers, "Definitely."
"Then you owe me $8.50. Your dog was loose and stole a roast from me today."
The lawyer, without a word, writes the butcher a check for $8.50. The butcher, having a feeling of satisfaction, leaves.
Three days later, the butcher finds a bill from the lawyer: $100 due for a consultation.
